I am starting TOG in two weeks with my 1st grade son (and K younger sister) and am wondering how necessary it is to do maps at all with one this young. Other than to help provide context of place and time, is it necessary that we take the time to learn all the geographical terms? Is that appropriate at this age? Should I do it over more time than 1 week, say over a month or unit? Suggestions and guidance are most apprciated.
